Come Play With Power

Looking to increase your V10's power output? Take a look at the Active Autowerke Signature V10 Power Pulley kit. It comes mostly with everything to make this installation simple and easy to install, it is also reliable and trouble-free. Best of all, it makes horsepower.


Purpose

When working on the BMW S54 engine of the E46 M3, Active Autowerke has found that additional horsepower can be attained with the installation of power pulleys. The S65 BMW V10 engine is no different where it also has to drive components like the the air conditioning and power steering. These ancillary components actually take away power because they create a load on the engine since they all share the same drive belt design. Active Autowerke has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. The end result is unleashing untapped power just by redesigning the the drive ratios of the engine pulleys. An additional 12+ horsepower is measured on our in house Mustang dyno when compared against a stock BMW V10.

What was a solid block of T6061 billet aluminum will now be transformed into precise component with a calculated pulley diameter, proper groove pitch, and true belt alignment with a calculated pulley offset. The exterior is also treated in a hard, black anodized finish that is strong and durable to give a smooth and quiet operation that will be trouble-free.

All the necessary parts are included in the kit making for a relative simple, easy installation that looks similar to factory when installed and it makes power. It can be fully reversible back to original if the need arises.

The power pulley is very modular in design and complements very well with other Active Autowerke performance products like the Active performance software or the Active performance exhaust. Truly a good start for the BMW M enthusiast.

I love this brand. These shoes look and fit great!
Size: 13 Wide, Color: Black/White/Black
I love wearing Cole Haan shoes. This is the second pair I’ve owned and the style just gets me. I’ve worn these to work at a great professional job every day, not just casual Friday. I wear these when I head out shopping or to dinner. They are functional, comfortable, built for regular and bigger wider feet and comfortable. I am 6 feet tall and my feet have changed size over the years to me needing a wider shoe to relieve pressure on my toes and front wide porting of my foot. So the 13W feels great and still walks the same as a regular 14 but more comfort for me. They look amazing and qualify in some offices as dress shoes (depending on company rules they will justify a sneaker as a shoe with the tan colored “gum” sole as a sneaker) so check company policy. The black sole on this makes it look more dressy. I am switching out the laces to match my previous Cole Haan because I think the white shoelaces look better. As an adult, aside from my Kenneth Cole boots Reaction boots and Doc Marten’s these are the only shoes I will pay 3 digits for. This looks like skater shoes but with a more mature look.

I am certainly glad I found them and finally ordered
Size: 10, Color: Ivory/White/British Tan
A bit bulkier than my Stan Smiths Leather versions, but actually more comfortable. They seem to be a bit "clunkier" looking than a streamline Stan Smith, but it's a matter of style. It works for a change of pace. Gets or picks up dirt a bit, but cleans well, except the canvas part. Has lasted almost 6-8 months with very little signs of wear. Feels very secure in any type of weather or condition. Great alternative or addition to having a pair of Stan Smiths.

Love the look, but Narrow
Size: 10, Color: Marine Blue/Woodbury/Ivory
What is for my son-in-law, he loves them, but had to switch them out twice because they run very narrow. He doesn’t have a wide foot at all so be careful when you purchase. Other than that they are a good looking shoe and he really likes them.

Awesome value shoes
Size: 11.5, Color: Ivory/White/British Tan, Size: 11.5, Color: Ivory/White/British Tan
These white Cole Haan shoes are just what I hoped for, the color is a perfect off-white, somewhere between cream and pure white, which gives them a more refined look. The quality feels excellent, they’re very comfortable right out of the box, and the laces feel durable and well-made. They fit true to size with no issues. Based on this experience, I’ll definitely be buying more from this brand in the future especially at this price point.
